Abstract Architectural techniques have evolved over the century. Presently, climatic conditions require architecture that is more adaptable to the environment. Coastal regions have been recognised to be the most vulnerable to the effects of climate change. Thus far, limited research has offered some strategies to mitigate the solar effect on thermal comfort and energy demand in coastal tropical regions. To address this problem, this study was conducted with the aim of evaluating, analysing, comparing, and discussing the impacts of passive strategies on thermal comfort and energy consumption (as well as the introduction of photovoltaic panels) in coastal tropical climate regions. All simulations were conducted for a period of one year using the Design Builder software. The results demonstrate that phase change materials (PCMs) have a significant effect on thermal comfort and energy consumption in an office under different coastal tropical climates. The combination of PCMs with thermal insulation has the ability to increase the comfort rate by up to 3% while decreasing the cooling energy consumption by approximately 12% in three studied climate zones. In a naturally ventilated building, the most significant increase in the comfort rate is observed with the introduction of PCMs in combination with thermal insulation, whereas thermal insulation, along with external shading, results in the most significant reduction in the cooling energy consumption of an air-conditioned office building (approximately 19%) in three studied climates. Furthermore, the introduction of photovoltaic panels enables us to generate 43–79% of the total energy consumption of the studied office building.

相变材料、隔热和外遮阳在不同沿海热带气候下的办公楼热舒适度改善和冷却能源需求减少中的应用

摘要 建筑技术已经发展了一个世纪。目前，气候条件需要更适应环境的建筑。沿海地区被认为是最容易受到气候变化影响的地区。迄今为止，有限的研究提供了一些策略来减轻太阳能对沿海热带地区的热舒适度和能源需求的影响。为了解决这个问题，本研究旨在评估、分析、比较和讨论被动策略对沿海热带气候地区的热舒适度和能源消耗（以及引入光伏板）的影响。所有模拟均使用 Design Builder 软件进行了为期一年的模拟。结果表明，相变材料 (PCMs) 在不同沿海热带气候下对办公室的热舒适度和能源消耗有显着影响。在三个研究的气候区中，PCM 与隔热材料的组合能够将舒适率提高多达 3%，同时将冷却能耗降低约 12%。在自然通风的建筑中，通过引入 PCMs 与隔热相结合，观察到舒适率的最显着提高，而隔热和外部遮阳则导致空气冷却能耗的最显着降低在三种研究气候条件下的办公楼（约 19%）。此外，
